Hi there ,We have recently purchased NHD-3.12-25664UMB3 OLED and are trying to interface it with Nvidia TX2 in SPI mode. So we need confirmation regarding the connection of Pin Number 19,20,21,22 {multi-font IC's } is it mandatory to use those pins ? OR they can be neglected like NC { No connection} OR can we connect those pins to ground ? . Because as of now we are not using Multi-font feature . Please confirm it at the earliest .
